DIE FOR FOLDING-MACHINES.

Specification of Letters Patent.

Patented Dec. 8, 1908.

To all whom it may concern:

Be it known that we, JOHN MAITLAND and WALTER J. BEATTIE, citizens of the United States, residing at Cohoes, county of Albany, and State of New York, have invented certain new and useful Improvements in Dies for Folding-Machines, of which the following is a specification.

The invention relates to such improvements and consists of the novel construc tion and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

Figure l of the drawings is a top plan view of the improved die. Fig. 2 is a central, vertical, cross-section of the same. Fig. 3 is a vertical, cross-section of the same taken on the broken line 33 in Fig. 5. Fig. 4 is a bottom plan view of the die with some of the parts removed from one end of the same for convenience in illustration. Fig. 5 is a similar view with other parts removed and certain parts partly broken away. Fig. 6 is an isometrical view of the die in inverted position with some of the parts removed. Fig. 7 is an isometrical view of one of the former-blocks with attached former plate.

This invention relates to improvements in machines for inturning the edges of fabric blanks in the manufacture of collars, cufis and like articles, and relates more particularly to the construction of die or former used insuch machines for accurately imparting the desired shape to the folded article.

In the drawings only the die or former is shown, other portions of the machine being omitted in view of the fact that they are well known to those skilled in the art and not necessary to be shown to afford a complete understanding of the present invention.

The die shown, described and claimed herein is adapted and intended for usein connection with a suitable bed, and folding and pressing mechanisms, which may be of any known form, the construction of said mechanisms shown and described in U. S. Letters Patent No. 666,766, granted to John Maitland and Walter J. Beattie, January 2-9, 1901, being well adapted for use in combination with the die or former forming the subject matter of the present application.

Referring to the drawings, 1, is the head plate of the die or former provided with screw-holes, 2, adapted to receive screws by which the die may be connected with the swinging frame, not shown, whereby the die or former is movable toward and from the bed of the machine in use.

The preferred form of die or former shown in the drawings is adapted for inturning the ed es of an article on all sides, the head-plate being provided in its underside or face with four diagonal guideway grooves 3, 4:, 5 and 6. Two of these grooves as, 3 and 4:, extend approximately to one end of the head, and the other two as, 5 and 6, extend approximately to the other end of the head, and each of said grooves crosses the other groove at the same end of the head, and one of the grooves at the other end of the head, and two of said grooves as, 3 and 6, are of greater depth than the other two grooves.

Movably mounted upon the underside of the head-plate are four diagonal slides 7, 8, 9 and 10, each having a rigid member or guide fitting and movable in one of said diagonal grooves which is adapted to form a guideway therefor. The said guide-members thus located in two diagonal guideway grooves which cross each other are movable in different planes and adapted to lap each other continuously, thus the guidemembers, 107 on the slide, 7, and, 109, on the slide, 9, occupy the inner portions of the deeper guideway grooves, 3 and 6, respectively, and are adapted to be lapped contiguously on their outer side by the guide-members, 108, on slide, 8, and, 110, on slide, 10, which occupy the shallower diagonal guideway grooves, whereby the guide-members which occupy the shallower guideway grooves serve to overlap and hold in place the guide-members in the deeper guideway grooves. The several guide members 107, 108, 109 and 110 are in effect integral withtheir respective slides 7, 8, 9 and 10, and are so shown in Fig. 3, but they may be made in any known manner.

The several diagonal slides 7, 8, 9 and 10, are extended laterally beyond the respective diagonal guideway grooves and are respectively engageable with the face or undersurface of the head-plate. Said diagonal slides are secured in position upon the face of the head-plate with their guide-members confined in the respective diagonal grooves by means of a pair of channeled face-plates, 11, secured by means of the screws, 13, to the underside of the head-plate at opposite ends thereof in engagement with the outer sides of the respective diagonal slides which are free to partake of slide-movements in the slideways thus formed between the face and head-plates. Each of said diagonal slides is provided near its outer end with a transverse groove, 14, in its inner surface, said transverse grooves in the diagonal slides, 9 and 10, at one end of the head being adapted to receive a cross-plate, 15, fixed upon a longitudinal slide, 16, fitting and reclprocatory in a longitudinal slideway, 17, in the face of the head-plate, and said transverse grooves in slides, 7 and 8, at the other end of the head being adapted to receive a similar cross-plate, 15, fixed upon the longitudinal slide, 16, fitting and reciprocatory in the longitudinal slideway, 17, in the face of the head-plate.

Each of the longitudinal slideways, 17, is provided with a longitudinal slot, 18, extending through the head-plate, through which slot said longitudinal slide is pivot 30. ally connected with one end of a link, 19,

' the other end of which link is pivotally connected with an operating lever, 20, fulcrumed at, 21, upon the back of the headplate, by operation of which lever, by hand 35,01 in any known manner, longitudinal reciprocating movements may be imparted through said links, 19, in opposite directions to the respective longitudinal slides, 16, which movements are transmitted through 49 the cross-plates, 15, to the respective diagonal slides, 7, 8, 9 and 10, to induce longitudinal reciprocating movements thereof with a resultant diagonal movement due to the confinement of the guide-members on said slides .in their respective diagonal guideway grooves. It is thus possible to secure contracting movements of the diagonal slides 7, 8, 9 and 10 from all corners toward the central portion of the head, and expanding 5o .movements thereof from the central portion of the head toward the corners by means of two link connections only with the operating lever, with the outer pivoted ends of the links traveling in straight lines longitudinally of the head.

The expanding and contracting movements are limited by means of the stops, 22 and 23, fixed upon the back of the headplate in the path of the lever, 20, the stop,

23, being made adjustable by means of the slot, 24, and bolt, 25, to permit the degree of expansive movement to be varied as desired.

To secure greater stability in construction and to afford a ready means for adjustably mounting the former-plates upon the diagonal slides, an outer channeled steadyplate, 26, is preferably fixed by means of screws, 27 upon each of the diagonal slides, 7, 8, 9, and 10, in position to inclose between said steady-plate and the slide with which it is so connected an intermediate portion of the channeled face-plate, 11, said steadyplate being adapted to engage and slide upon the outer surface of the face-plate. Each of said channeled steady-plates has a depending flange, 28, provided with longitudinal slots, 30, through which are inserted screw-bolts, 29, which connect with the respective former-blocks, 31, having on their outer sides offsetting former-plates, 32, the outer edges of which former-plates, when the die or former is expanded, together make up the outline or contour desired for the folded article.

The former-block is preferably made of a plate of metal, as steel, split partway of its length with its upper branch left in its original plane and adapted to be clamped by means of the screw-bolts, 29, firmly against the side of the flange, 28, on the channeled steady-plate, and having its lower branch offset from said plane and bent to conform jointly to the edge line of the former-plate to be connected therewith.

The outer ends of the branches of the split former-block are rigidly connected together by means of a brace 33.

The formerplates have integral portions, 34, offset at right angles and secured directly to the side of the former-block.

What we claim as new and desire to secure by Letters Patent is 1. In a die or former for folding machines and in combination, a head-plate and a face-plate secured together with a slideway and a diagonal guideway therebetween; a slide movable along said slideway between said plates and wholly beneath said headplate and having a guide movable along said guideway; a former-plate mounted upon said slide; and operating mechanism mounted upon the back of said head-plate and connected with said slide.

2. In a die or former for folding machines and in combination, a head-plate and a faceplate secured together with a slide-' way therebetween; a slide movable in the slideway between said plates; a steady-plate fixed to said slide and movable along the underside of the face-plate; a former-plate mounted upon the said steady-plate; and operating mechanism mounted upon the back of the head-plate and connected with said slide.

3. In a die or former for folding machines and in combination, a head-plate and a face-plate secured together with a plurality of slideways and a plurality of diagonal guideways therebetween; a plurality of slides movable along the respective slideways between said plates and wholly covered by said head-plate, and each having a guide movable along one of said guideways; a plurality of former-plates mounted upon the respective slides; and operating mechanism mounted upon the back of the head-plate and connected with the respective slides.

In a die or former for folding machines, and in combination, a head-plate provided in its face with a diagonal slideway groove; and a channeled face plate secured upon the underside of the head-plate bridging the grooved surface thereof; of a slide having two rigidly connected members, one fitting and movable in said diagonal groove, and the other extending laterally to bear upon the face of the head-plate on opposite sides of said groove between said head and face-plates; a former-plate mounted upon said slide; and operating mechanism mounted upon the back of the head-plate and connected with said slide.

5. In a die or former for folding machines, and in combination, a head-plate provided in its face with intersecting diagonal grooves of different depths; a pair of slides each having a guide-member fitting and movable in one of said intersecting slideways; said guide-members being located in different planes and lapping each other con tiguously; a face-plate secured to the underside of the head-plate in engagement with the slide having the outer of said lapping guide-members; a pair of former-plates mounted upon the respective slides; and means for operating the respective slides.

6. In a die or former for folding machines, and in combination, a head-plate provided in its undersurface with a pair of diagonally arranged slideway grooves, and intermediately thereof with a longitudinally slotted slideway; a pair of slides movably mounted upon the face of the head-plate having portions fitting and movable in the respective diagonal grooves, said slides being provided in their inner surfaces with transverse slideway grooves and being wholly covered by said head-plate; a pair of former-plates secured to said slides respectively; operating mechanism mounted upon the back of said head-plate; a slide movable in said longitudinal slotted slideway having laterally extending portions occupying the transverse slideway grooves in said pair of slides, and connected with said operating mechanism; and a face-plate fixed to the underside of said head-plate in engagement with said pair of slides.

In testimony whereof, we have hereunto set our hands this 12th day of March, 1904.
